ABSTRACT OF THE DISCLOSURE Disclosed are concrete and mortar compositions for wet spraying, that have prolonged setting times (retarded long enough to be delivered from a ready mix plant to a construction site and remaining workable for up to 2 days thereafter), but which can be brought to immediate stiffening, setting and quick hardening by the addition of certain setting accelerators, particularly those based on potassium aluminate.
